A home in Winchester, VA had an attic with very little insulation. The Comfenergy Crew came out and properly air sealed and insulated the attic. Insulating your attic can help prevent air from escaping the house and stop outside air from coming in. Heating and cooling costs account for up to 50-70 percent of the energy used in an average home.

A home in Winchester, VA was experiencing unbearably hot top floors during the summer months. The master bedroom was the worst - sometimes, the homeowners had to sleep in the downstairs guest bedroom to escape the heat! 

It came as no surprise to us that the attic had insufficient and almost non-existent insulation. It also had a vent that was directly allowing outside air in! It's no wonder that the rooms under this attic would be having these issues. 

To fix this problem, we first air sealed leakage points with spray foam. We then blew in a thick layer of cellulose insulation through the entire attic. This attic is now a conditioned space and won't contribute to comfort/efficiency problems any more!

Expert Spray Foam Insulation Company

At one point pink fiberglass insulation was the best option for home insulation. However, today spray foam insulation is the much better option. Spray foam insulation has several benefits and beats the traditional fiber-glass product in every way. Spray foam insulation is the top choice for homeowners, contractors, and building scientists (the experts who study home energy performance) for several reasons. Here are the top reasons spray foam insulation should be your number 1 choice:

Advantages of Spray Foam Insulation:

  • Provides both insulation and air sealing
  • Fills gaps and cracks
  • High R-value
  • Speedy installation
  • Spray foam won't shift, settle, or fall out of place

Crawl Space Insulation Experts

Do you need crawl space insulation installed or replaced? If so, you're in the right place! A damp crawl space with falling or sagging insulation usually means the space has a moisture problem. If that is the case our team of experts can provide a vapor barrier to keep moisture out of your crawl space. We can then replace your existing insulation with a better option such as rigid foam or spray foam insulation. If your crawl space is completely missing insulation then your home is most likely cold and drafty. This is because the environment in your crawl space will transfer to other parts of your home, which is why proper crawl space insulation is essential to keeping your home comfortable and your energy bills low. To learn more about crawl space insulation cost, call, or click today!

Job Stories From Winchester, VA
Reinsulating an unfinished attic

These Winchester homeowners live in a small cottage that was built by a personal contractor. Since moving in, they have realized that the cottage is poorly insulated and the temperatures in the home were not consistent and uncomfortable. Our sales professional performed an inspection of the house and determined that the homeowners needed to have the current Batt insulation removed and replaced with our TruSoft cellulose insulation. We blew in the TruSoft cellulose between the attic rafters. To keep the attic completely air tight and conditioned, we air sealed the attic floor with ZypFoam and sealed the can light covers as well. Now this home is comfortable year round!

I recently purchased a 95 year old home in Winchester and my electric bills are through the roof.

Please contact me at your earliest convenience to set up a consultation. Thank you.
